T0 oswa'nn SPIRAL-SPEING-WINDING- DEVICE.

To allcuhom itmag concern 7 Be it known that I, .GIORD'ANO ZILoooKI,

- a citizen of Italy, andresiding at New: York,

in the county of New York and State of New York, have invented certainnew and useful Improvements in' Spiral:Spring- Windin r Devices, ofwhich the follow ng is a speciiication, such as will enable thoseskilled in the, art to which it appertains to make and use the same. a

Th1s lnvention relates to .tools foruse in winding wire on a mandreltoform wire jects in view the invention consists in a tool 1 tionandefiicient in use, and which is con-. structed and operated ashereinafter deof the class and for the purpose specified which is simplein construction and operascribed and claimed;

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are des1gnated by suitable reference characters ineach of the views, and inwhich Fig. 1 is a plan View of my improved toolandv diagrammatically illustrating the methodof its use;

' Fig. 4 a view similar to Fig. 3 but showing the gage in a differentposition; and,

i Fig, 5 a bottom plan view of the gage device shown in detail in Figs.3 and 4c.

For thepu-rpose of illustrating the use of my invention, I haveindicatedat 10 inthe accompanying drawing a mandrel which is adapted to berotated by a suitable machine, such for example, as a'lathe,.and to oneend portion of which is secured a collar '11. My

improvedtool 12 is adapted'f or use in connection with the mandrel l0and comprises Specification of Letters Patent.

Application filed December-7, 1920. Serial No. 429,029.

a partial section on the line22 of.

Patented Apr; is, 1922.

with which a handle member 14 is connected, and the cross head 15 ofthebody portion 13 is provided with an 'aperture'lti'adapted to receive acylindrical bushing 17 held in place by a set screw 18. I

The bushing 17, or the aperture 19 there of, is slightly greater indiameter than the (.lMJHBtGP'Of the mandrel 1O employed, the extent ofthis difference being determined by. the diameter of the wire 20employed.

The cross head 15 is providedwith an aperture121 and the bushing 17 witha corresponding aperture 22 to permit of the passage of the wire 20in'to'the aperture 19 and around the mandrel 10, as hereinafter set out.The body portion 13 is enlarged centrally as indicated at 23, and asleeve 2L-is adjustably mounted therein and held in different positionsof adjustment by a lock member 25, and a gage device 26, in the form ofa screw, :isadjustably mounted in the sleeve 24: and held indifferentpositions of adjustment by a lock member 27. The inner face of the gagedevice is provided with a comparatively thin transverse projection 28which is adapted to' cooperate with the periphery of'the mandrel 10, ashereinafter set out. The lock members25 and 27 body portion 13 withoutrotating the same in this operation, and this will be necessary in orderto permit of the winding of a single coil, the separate coils-of which,or the dis I tance therebetween will vary, in other words,

aflsingle coil may be produced with both closely arrangedand widelyspaced coils therein. 7 7

The use of my improvedtool-will be readil understood from the foregoingdescription when taken in connection with the'accompanyin drawing andthe following statement. fter the tool 12 has been mounted on themandrel 10 and the mandrel placed in 'a suitable machine, the free endofthe wire 20 is passed inwardly through thev apertures '2122 around thetransverse projection. 28 and. laterall through the aperture 19 ofv thebushing 1 and is secured n app ly T shaped bodypo ti 1 q e 9 3 -as shownat 31 in Fi 1' of body portion and provided with an aperture,

the drawing, the tool 12 being in juxtapd sition to said collar in thisoperation. .The mandrel 10 is then rotated by the machine in which it ismounted and the wire 20 will be wound upon said mandrel to form a spiralcoil 82, and the operation of winding the wire 20 upon the mandrel 10will auto-matically feed the tool longitudinally of said mandrel." Thedistance between the separate coils of the spring is regulated by a gagedevice 26, or the relative position of the transverse projection 28thereof to the longitudinal line of the mandrel, and by means of theadjustable or radially movable gage device, I may wind upon the mandrel10 in one operation a coil or wire, the distance between the separatecoils or windings of which may be of the same dimensions throughout, ormay vary, if desired, in other words, a part of the coil. may be woundas shown in Fig. 3 of the drawing and another part as shown in Fig. 4 ofthe drawing, or a complete coil may be wound as shown in Fig. 3 or Fig.4, it being understood that differently spaced coils than those shown insaid figures may also be wound on the mandrel by reason of theadjustment of the gage device 26. Y It will also be apparent that'thebushing 17 shown in the accompanying drawing may be removed, wheneverdesired, and another bushing employed having apertures 19 of differentdimensions, in which event the diameter of the mandrel employed willalso be varied to correspond with the sides of the aperture in thebushing employed, as well as the size or gage'of the wire employed, andwhile I have shown certain details of construction for carrying myinvention into effect, it will be understood that various changestherein and modifications thereof may be'mad'e, within the scope of theappended claims, without departing from the spirit of my invention orsacrificing its ad vantages.

Having fully described my invention,

what I'claim as new and desire to secure by.
